* configure.ac (USE_NCURSES): New symbol.
* src/dispnew.c (init_display): Depend on USE_NCURSES, not GNU_LINUX,
to decide whether ncurses is being used.  Without this change,
GCC complains about tgetent not being declared, on a system
that has tinfo installed but ncurses not installed.

* gnus.el (gnus-continuum-version):
* gnus-msg.el (gnus-extended-version): Simplify.

* gnus.el (gnus-continuum-version-1): Remove.

(Fdefconst, FletX, Flet, Fwhile, Fcatch, Funwind_protect)
(Fcondition_case):
Tune by taking advantage of the fact that ARGS is always a list
when a function is declared to have UNEVALLED args.

GCC 4.6 complains about -Wunused-local-typedefs, introduced in 4.7.

* gnus.el (gnus-continuum-version): Do main calculations in integers.
  (gnus-continuum-version-1): New function, return a string.
* gnus-msg.el (gnus-extended-version, gnus-bug):
  Use gnus-continuum-version-1 instead of gnus-continuum-version.

autoload--insert-cookie-text.

Move the `setq success'.
(url-http): Use pcase.
(url-http-file-exists-p): Simplify.

(desktop-before-saving-frames-functions): New hook.
(desktop--process-minibuffer-frames): Set desktop-mini parameter only
for frames being saved.  Rename from desktop--save-minibuffer-frames.
(desktop-save-frames): Run hook desktop-before-saving-frames-functions.
Do not save frames with non-nil `desktop-dont-save' parameter.  Filter
out deleted frames.
(desktop--find-frame): Use cl-find-if.
(desktop--select-frame): Use cl-(first|second|third) to access values
of desktop-mini.
(desktop--make-frame): Use cl-delete-if.
(desktop--sort-states): Fix sorting of minibuffer-owning frames.
(desktop-restore-frames): Use cl-(first|second|third) to access values
of desktop-mini.  Look for visible frame at the end, not while

buffer-lists when restoring frames.  Suggested by Martin Rudalics.

It was inadvertently omitted.  It's needed only if
HAVE_MENUS && ! (USE_X_TOOLKIT || USE_GTK).

* callproc.c (child_setup): When the child's exec fails, output
the program name, as that's more useful.  Use O_NONBLOCK to avoid
deadlock.
* process.c (create_process_1): Remove; no longer needed.
(create_process): Remove timer hack; no longer needed, now that
the child avoids deadlock.

(desktop--filter-iconified-position): New function.
(desktop-filter-parameters-alist): Add entries for `top' and `left'.

* lisp/image-dired.el (image-dired-track-original-file):
Use with-current-buffer.

(allocate_pty): Define even if !HAVE_PTYS; that's simpler.
Take pty_name as an arg rather than using a static variable.
All callers changed.
(create_process): Recover pty_flag from process, not from volatile local.
(create_pty): Stay inside array even when pty allocation fails.
(Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.

Mention that it's needed only for older GCCs.
